HP StorageWorks 4400 Scalable NAS for File Serving cluster configuration guide (AN595-96004, September 2008)

5. Create the new filesystem with the appropriate options such as block size and d isk quotas. See
“Configure PSFS Filesystems” in the HP Clustered File System administration guide.
6. On Windows systems, associate the filesystem with a drive letter or m o unt path, which provides
access to the filesystem. On L inux systems, mount the filesystem with the appropriate mount options.
See “ Configure PSFS Filesystems” in the HP Clustered File System administration guide.
Membership pa
rtitions
HP Clustered F
ile System uses a set of membership partitions to control access to the SAN and to store
certain cluster configuration information. The membership partitions are located on three 1GB vdisks
in the array. Write access to the membership partitions is disabled to prevent accidental corruption
from other ap
plications.
Membership partitions can be added, replaced, or repaired as necessar y. For more information, see
“SAN Maintenance” in the HP Clustered File System administration guide.
Fencing
When certain problems occur on a server (for example, hardware problems or the loss of cluster network
communications), and the server ce ases to effectively coordinate and communicate with other servers
in the cluster, HP Clustered File System must remove the server’s access to filesystems to preserve data
integrity. Thisstepiscalled fencing.
The fencing m etho d configuredonHPStorageWorks4400ScalableNAS systemsiscalled fabric-based
fencing. When it is necessary to fence a server, HP Clustered File System disables the ser ver’s access in
the Fibre Channel fabric. The server must be rebooted to regain access to the SAN.
Hardware snapshots
HP Clustered File System is configured to take hardware snapshots or snapclones on the EVA 4400
array. For more information, see “Manage Hardware S napshots” in the HP Clustered File System
administration guide.
Performance changes for NFS (Linux only)
The HP StorageWorks 4400 Scalable NAS system has been tuned to p rovide a better general starting
point for NFS operations. The tunings apply to settings for the Ethernet ports, to the TCP software stack
operations, and to virtual memory handler in the OS. These changes enable much better I/O through the
NIC interfaces on the system.
Stand-alone version of HP CFS Management Console
The HP
CFS Management Console is available in a stand-alone version that can be installed on an
Windows system outside the cluster.
On the Linux version of HP StorageWorks 4400 Scalable NAS, the console file is provided on the
clust
er servers at:
/opt/hpcfsmgmt/tools/mxconsole-3.5.1-414.msi
On the Windows version of HP StorageWorks 4400 Scalable NAS, the console file is provided on
the cl
uster servers at:
C:\Program Files\Hewlett-Packard\HP Clustered File System\Management
Console\MXCONSOLE.MSI
